东北地区城市韧性时空特征分析

Spatio-Temporal Characteristics of Urban Resilience in Northeast China

为了使得城市能够应对其形成和发展过程中所面临的各种冲击和挑战,必须提高城市的抗冲击能力和恢复能力,也就是提高城市韧性。本文利用层次分析法,对我国东北地区的城市韧性进行综合测算,并对其时空特征进行分析:① 从时间特征来看:总体来看,2003~2017年东北地区整体的城市韧性有所提高,分省份来看,2003~2017年辽宁省的城市韧性有所下降,吉林省和黑龙江省的城市韧性则有所提高;② 从空间特征来看:东北地区城市韧性的空间分异特征显著,辽宁省的城市韧性最高,吉林省次之、黑龙江省的城市韧性最低;省会城市和副省级城市大连、资源型城市大庆的城市韧性要高于一般城市;位于边缘地区,距离省会城市较远的城市,受到辐射带动能力较弱,城市韧性较低。③ 对于不同城市,影响其韧性水平的因素不同。

In order for cities to cope with the various shocks and challenges faced in the process of their formation and development, it is necessary to improve the impact resilience and resilience of cities, that is, to improve urban resilience. This paper uses the analytic hierarchy method to comprehen-sively calculate the urban resilience in northeast China, and analyze its spatio-temporal characteristics: 1) From the perspective of time characteristics: Overall, the overall urban resilience of northeast China has improved from 2003 to 2017, and from the perspective of provinces, the urban resilience of Liaoning Province has declined from 2003 to 2017, and the urban resilience of Jilin Province and Heilongjiang Province has improved;2) From the perspective of spatial characteristics: the spatial differentiation characteristics of urban resilience in Northeast China are significant, with Liaoning Province having the highest urban resilience, followed by Jilin Province and Heilongjiang Province with the lowest urban resilience;the urban resilience of provincial capital and sub-provincial city Dalian and resource-based Daqing is higher than that of general cities;cities located in marginal areas and farther away from provincial capitals have weak radiation driving capacity and lower urban resilience. 3) For different cities, the factors affecting their resilience level are different.
